SPECIFICATION forming part of Letters Patent No. 636,518, dated November '7, 1899.

Applicationfiled Mayl, 1899. Serial No.715,1'77. (NomodeL) To all whom it may concern:

Be it known that I, GEORGE W. GOLDEN, a citizen of the United States, residing-at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Window-Guards, of which the following is a specification, reference being had therein to the accompanying drawings. Y

My invention relates to window-guards; and the object of the invention is to provide means for elfectually preventing dust and dirt from passing through the crevices between the sash and frame, and, further, to prevent binding of the sash.

The invention consists of the construction and arrangement of two -strips having longitudinal sliding engagement with each other and secured, respectively, to the sash and frame, one of said strips being laterally pressed against the other.

The invention further consists in the peculiar arrangement and combination of parts, as more fully hereinafter described and claimed.

In the drawings, Figure 1 is a horizontal section through a window frame and sash to which my improvement is applied. Fig. l

is a similar view showing a slightly-modified construction. Fig. 2 is a vertical section on line a; m, Fig. 1; and Fig. 3 is a perspective view of the two members comprising the guard, also slightly modified in construction.

My guard comprises two members A and B, having a longitudinal sliding engagement with each other. The member A preferably consists of a metallic bar substantially U- shaped in cross-section and laterally slidingly secured in the groove 0, formed either in the sash or the frame; In. the drawings I have shown this groove as formed in the sash, and the channel-barA is secured in position therein by means of the headed pins D passing through apertures in the bar and driven into the sash-rail. The member A is pressed into engagement with the'member B by springs, which in Fig. 2 I have shown as flat elliptic springs E, arranged between two of the guidepins D, which will serve to hold said springs a b are provided with inwardly-projecting flanges c, or as shown in Fig. 3, in which said side flanges are provided with beads or rounded bends d. The memberB consists of abar havinga portion esubstantially Wedge-shaped in cross-section, against which the sides of the bar a are adapted to bear, and a portion f, which forms a securing-flange and is attached in any suitable manner to the frame orsash.

With the parts constructed as thus far described it will be readily understood that the bar A will be pressed against the wedgeshaped portion of the bar B by the springs E, which will thus form a tight joint between the two bars, preventing the passage of air or dust. At the same time as the members A are free to yield thesash will slide freely and, if desired, the usual stops F and G may be omitted, as shown on the right hand of Fig. 1, the guard forming the slides for the sash.

What I claim as my invention is- 1. A window-guard comprising two strips longitudinally slidingly engaged with each other and secured respectively to the frame and sash, one of said strips being a channelbar and the other having a wedge-shaped cross-section against which the edges of said channel-strip are adapted to bear and a spring for pressing one strip laterally against the other.

2. A window-guard comprising a channelbar laterally slidingly engaging with a groove in the sash with its flanges extending outward, a spring for pressing said channel-bar outward, and the bar B secured to the frame having the wedge-shaped portion 6 adapted to slidingly engage with said channel-bar and securing portion f.

In testimony whereof I affix my signature in presence of two witnesses.
